I need help setting up a custom protocol and delegate

Hi, I'm working on an app that shows government information. One part is a "Representative Finder" in which someone can enter their address, press a button, and see who represents them. The base of this is a VC with a table that lists the results, and the search box is in an embedded container view. I'm having trouble setting up the delegate/protocol to transfer the data from the embedded TextField to the UITable in the root VC. My code is as follows:

SEARCH VC: ``` import UIKit

      protocol LocalSearchInputDelegate: class
      {
          func showString(data: String)
     }

      class LocalSearchWindow: UIViewController {




weak var textDelegate: LocalSearchInputDelegate?

@IBOutlet weak var localSearchText: UITextField!

@IBOutlet weak var localSearchButton: UIButton!

func buttonPressed(sender: UIButton)
{
    print("spot1")
    textDelegate?.showString(data: "ooh rah")

}


override func viewDidLoad() {
    super.viewDidLoad()
    //textDelegate=currentVC as! LocalSearchInputDelegate
    localSearchButton.addTarget(self, action: #selector(buttonPressed), for: UIControlEvents.touchDown)

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}```

TABLE CONTROLLER:

         ```class RepresentativeFinder: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource, UITableViewDelegate,    UITableViewDataSource, LocalSearchInputDelegate {

          func showString(data: String) {
          //These commands don't work       
         print("your data is")
               print(data)
              }```
